Thanks Erik, glad you like it.
A reel of product commercials has been a standing fixture in UK cinemas since the 1960s - there are many whole reels (of various vintages) on Youtube if you go looking. The cigarette industry in particular thrived in this arena (especially in the period after tobacco advertising was banned on television) hence the very creative and expensive commercials on display here.
Re. the Star Trek trailer, this is from the DVD, and has a 5.1 mix - the strange panning was part of the original (though here it's folded down to simple stereo).
The Black Hole trailer is also from DVD. I haven't been able to find a 16:9 version anywhere, and cropping would destroy the (already cut-down) image so I had to leave it as-is - not very satisfying, I know. Any thoughts on where I might find a widescreen version?
